Is there a single relay that controls the rear wiper and washer? They both crapped out at exactly the same moment - I was driving along, used the washer and wiper (both worked fine) then went to them it again and... nothing. I can hear a "click" when i press a button but nothing happens. Is there a single relay that could have tanked and is causing both to not work? If so, does that relay control anything else?

Thanks in advance -
